EnvelopeMailService wurde umgestaltet, um gemeinsam genutzte Veränderungen des _placeholders-Wörterbuchs zu vermeiden.
Die Konfigurationseigenschaft MailParams.Placeholders wurde von einem veränderbaren Dictionary<string, string>
zu einem ImmutableDictionary<string, string> geändert, und _placeholders wird nun bei der Dienstkonstruktion als neues Wörterbuch instanziiert.
